There are 2 UMDs. A movie and a game for the PSP. I didn't know if that is qualified as being retro, but it sure was a crazy media format to distribute stuff. Weird.
I got some original Gameboy cartridges, and a GBC game that seems to be defective. But I will open the cartridge and see if I can repair it.
The NES module couldn't be tested, but it is in good condition from outside.
A bunch of PS 1 memory cards and V-Rally rounds this loot up😉.
